GAS-REGULATOR FOR BURNERS. Y

SPECIFICATION forming part of Letters Patent No. 740,163, datedSeptember 29, 1903.

Application iiled March 30, 1903. Serial No. 1501177 (No model.)

To vall whom, it may concern: Y'

Be it known that I, GORGE F. MOORE, a citizen of the United States, anda resident of Milwaukee, in the county of Milwaukee and State ofW'isconsin, have invented certain new and useful Improvements inGas-Regulators for Burners; and I do hereby declare that the followingis a full, clear, and exact description thereof.

My invention has for its object to provide a simple and effectivegas-regulatorfor burners and is adapted to be interposed between thedischarge of a gas-bracket and the burner, and it is especially designedto be used in connection with incandescent gas-burnerssuch, forinstance, as patented by lvm. Trice, May 25, 1897, No. 583,344-where theflow of gas is determined by the size of holes in the tip. vThese holeswhen of less area than is required to make a perfect light consistentwith the gas-pressure are enlarged to suit the condition, and when thegas -pressure increasesit will be seen that the holes are too great inarea, and consequently the burneris then rendered useless. Under theseconditions by attaching one of my devices to the aforesaid burner itregulates the supply of gas to the required amount and for all practicalpurposes makes the said burner as edective as a new one. Y

A further object of my invention is to provide a regulator for the'ordinary gas-burner where the tips are unnecessarily large for lightingpublic halls, dto.; and it consists in certain peculiarities ofconstruction and coinbination of parts to be fully set forth hereinafterwith reference to the accompanying which has a handle c projectingthrough a horizontal slot o in the thimble A for engagement witha hollowvspool G. This latter is provided with a central sleeve c, which turnsupon the periphery of the aforesaid thimble and has an aperture d,through which the handle a of disk F protrudes.

The upper disk E rests upon the face of the lower disk and has a tongueA', which is slightly bent for engagement with a vertical offset II ofthe slot b, and both disks, as best shown in Fig. 2 of the drawings, areprovided with radial openings e j", respectively.

A threaded hollow plug I is fitted into the upper end of the thimble A,having its lower end faced Vand resting upon the disk E, so as to holdthe latter, together with disk E, into the countersunk seat g. Ashoulder of saidplug rests upon the upper face of the thimble andprevents the former :from cramping the disks upon their seat.l

The upper portion of plug I is threaded to receive the gas-burner and,as illustrated in Fig. l of the drawings, is iitted with an incandescentburner-tube ,7' with a regulator opening K. A partition L below the sameis provided with the usual orifices through which the gas is fedA to theburner.

From the above description of the several parts it is obvious that byturning the thim ble the flow of gas can be regulated or cut Offentirely by means of the lower disk F being turned to open or close theradial openings in the upper disk E, which is held stationary by reasonof 'the tongue a' entering the recess H, and to prevent any escape ofgas the spool is made air-tight, so that should any drawings, andsubsequently claimed. escape through the horizontal slot l? it is con-9o In the drawings, Figure l is a vertical sec-l fined within the saidspool. 4o tion of my device indicated on line 1 l of Fig. To assemblethe parts, (the plug I being re- 3, with a portion of an incandescentburner in moved,) the spool is iirst slipped on and the place. Fig. 2 isa plan sectional vieur on the disks are then dropped into their seat intheir line E? 2 of Fig. l 5 and Fig. 3 is a detail elevaorder, theoffset H of slot b performing a 95 tion of the same partly broken awayand in section on theline 3y 3 of Fig. 2.

Referring by letters to the drawings, A indicates a thimble which isinternally threaded at B Gand has a central shoulder D. The latter isbored out to form a gas-passage and its upper face is countersunk at gfor the reception of a pair of disks E F, which together Y form a valveand seat, the lower disk F of doing away with pivot-pins for the valveor other complication which would be expensive to construct and whenused liable to get out of order.

IOO

Having thus described my invention, what Patent, is-

l. In a gas-regulator for burners an internally threaded thimble havinga central shoulder, a pair of disks, having openings therein restingupon said shoulder, a horizontal slot provided with a vertical offset inthe thilnble, a handle projecting from the lower disk through thehorizontal slot and a tongue projecting from the upper disk and into theaforesaid vertical offset, a hollow spool having a central sleeve iittedupon said thimble and an aperture in the sleeve for engagement with theaforesaid disk -handle, and hollow threaded plug iitted into the thimbleabove the shoulder whereby the disks are held in place, substantially asset forth.

2. In a gas-regulator for-burners an internally threaded thimble havinga shoulder therein and a horizontal slot, valve-disks having openingstherein resting upon the shoulder, a hollow plug fitted into thethimble, whereby said disks are held in place, a handle projectingfrolnone of said disks and through the aforesaid slot, means for holdingthe other disk against vertical movement and a spool fitted upon theexterior of the thimble for engagement with the said disk-handle,substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand, atMilwaukee, in the county of Milwaukee and State of Viscousin, in thepresence of two witnesses.
